just curious, why do they call it a "swap"? Isn't it just an insurance policy?

(I always have to draw the cash flow map in my head.

I pay cash to a risky somebody on credit, hoping I make some interest. I also pay for an insurance policy (a hedge?) for if the debtor defaults. If my debtor defaults, my insurance policy pays me the cash instead. Something like that.

Is life insurance a swap? Like, if I die, my family swaps me for some cash?)
